I dont think you will get exactly what you are looking for out of the box but you can try creating a listview ( GANTT VIEW) on your task list.This could give you somewhat bar-chart kind of a thing.

If you are fine with custom coding then you can create DATAVIEW using Sharepoint Designer and play around with the formulas to create it. Search on net for using DataView for custom views, you should get some articles.
